Induction Dose Recommendations
Dogs and Cats
Administer one quarter of the calculated dose every fifteen seconds, until the patient can be intubated. Premedication may result in significant dose requirement reduction.

Cat Induction Dose
Un-Premedicated | Premedicated |
5 mg/kg | 5 mg/kg |
0.5 mL/kg | 0.5 mL/kg |

Dog Induction Dose
Un-Premedicated | Premedicated |
3 mg/kg | 2 mg/kg |
0.3 mL/kg | 0.2 mL/kg |

At induction, IV injection speed should result in the total dose, if required, being administered over a period of 60 seconds.

* This is lower than the labelled (SPC) premedicated dose for Alfaxan® Multidose and the dose may be further reduced if alpha-2 agonists or acepromazine have been administered.
Preoxygenation is essential
Administer one quarter of the calculated dose every 20-25 seconds flushing the intravenous cannula after each increment. Continue until stage III anaesthesia has been achieved.
